[0131]Hydrocracking Reaction Using Mo(C0)4(TOP)2
[0132]Step 1. To a 100 mL Schlenk tube substituted with argon, 1 g (3.8 mmol) of Mo(CO)6 and trioctylphosphine were dissolved in 10 ml of diethylene glycol dimethyl ether, and the reaction was performed at 150° C. for 20 hours. After the reaction, a supernatant was removed, and precipitates were washed once with distilled water and three times each with ethanol and ethyl ether and dried, thereby preparing a catalyst precursor for a hydrocracking reaction (Mo(CO)4(TOP)2).
